I got a call from 402-970-4078 @ 5:59 am. and I shut it down cause the number was unfamiliar to me, and the timing was ridiculas and stupid. i research the no, for sure it's a scam.
This is a legitimate number held by a large brokerage firm TD Ameritrade. It is their, as the previous post indicated, customer service number. If there was a telemarketer using number they are spoofing it.
